QuestionThe rows/data that were displayed on Cleaning step of Tableau Prep Builder disappear when they are actually output from the flow.
The People data/table shown in the Superstore example below is intentionally set the "Number of rows" to 2 in Data Sample setting in Tableau Prep. This is an issue that occurs when the data is large enough to be "sampled"
- Orders : Having all Region in real.
- People : Sampled only East and West rows from Region field (having all Region in real).
However, If user run the flow, the output row will be 0 records because all value in Region field are matched.
